Totally fun, but gets repetive real fast
You are some guy who has to infiltrate Hitlers castle and kill some people, that about it. The bosses are fun and so are finding all the hidden passages, but thats it. There are a range of cool weapons, but there are only 4 or 5 guns to collect, that it then you have them all.
I guess this was fun to me when I was a kid cause it was a violent video game, but even then it was dumb and cruddy.
In conclusion only get this game if you are curious or something like that.
